Our work investigated how six primary school students used a non-traditional method for adding and subtracting: the ABN method, a Spanish acronym for Open (method) Based on Numbers. Commognitive theory [Sfard, A. 2008. "Thinking as Communicating: Human Development, the Growth of Discourses, and Mathematizing." New York: Cambridge…

The National Council of Teachers of Mathematics (NCTM) emphasizes the teaching of "Big Ideas" in mathematics. This study focuses on the part-part-whole (PPW) relationship as a crucial aspect of word problem solving involving addition and subtraction. This study, conducted in the United States, evaluated the effects of conceptual…

Elementary school students with or at risk for emotional and behavioral disorders (EBD) are likely to experience social difficulties and challenges with peer relationships (e.g., victimization, rejection, isolation, and negative peer influence). A particularly salient influence on students' classroom-based social experiences is how they are…

Mathematical word problems present various challenges for students, including English learners. Research on word problem-solving interventions for elementary English learners with or at risk for mathematics disabilities/difficulties was reviewed. A systematic search of studies conducted between 2012 and 2022 yielded a total of 14 research studies…

The purpose of this mixed methods study was to investigate the implementation of a researcher-created numberless word problem instructional unit designed to introduce second-grade students to word problems in the semantic category of "compare with the word more, smaller unknown." The 10-day instructional unit incorporated three elements:…

Previous research examining comparison relations in word problems primarily focused on students' achievements in word problems with one operation. In this paper, we extend previous research to examine the achievement of students of different ages on word problems that integrate compare and combine word problems, hereafter referred to as…

Little is known about mismatches between the language of mathematics testing instruments and the rich linguistic repertoires that African American children develop at home and in the community. The current study aims to provide a proof of concept and novel explanatory item response design that uses error analysis to investigate the relationship…

A theoretical framework grounded in constructionism and pragmatism theories supported research on learning by doing. This framework underpinned the purpose of this qualitative case study to explore how K-8 STEM teachers facilitated projects utilizing innovative technologies to solve community-based problems. The problem was a lack of connection…

This cohort-sequential study explored the working memory (WM) structures that underlie growth in mathematical word problem solving (WPS) performance in elementary school emergent bilingual children whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 in southwest U.S. school districts at Wave 1 were…

There is a need to provide evidence-based social, emotional, and behavioral interventions for learners at risk for emotional and behavioral problems. Evidence-based interventions for social and emotional success are especially necessary for Black learners with emotional or behavioral problems. In the current study, we used a multiple-baseline…

Solving arithmetic word problems has been a challenge for primary students due to difficulties in understanding the problem structure and relating the quantities in the problem to each other. This paper reports on an action research study to enhance students' subtraction word problem-solving skills. The authors observed that their students had…

The decomposition of numbers when solving subtraction tasks is regarded as more powerful than counting-based strategies. Still, many students fail to solve subtraction tasks despite using decomposition. To shed light upon this issue, we take a variation theoretical perspective (Marton, 2015) seeing learning as a function of discerning critical…

Current research has established that inclusive schooling alone cannot ensure the social participation of all children -- a central goal of inclusive education. Therefore, this study examines whether the participation of students is dependant on the type of difficulty they experience (learning vs. behavioural) and the degree of class cohesion.…

This study's purpose was to investigate effects of 3 intervention approaches for building working memory (WM) and improving word-problem solving (WPS). Children with mathematics difficulties (n = 240; 7.51 years [SD = 0.33]) were randomized to 4 conditions: a control group, general WM training with contiguous math practice, WPS intervention…

Connecting literacy to social issues such as gender stereotypes supports reading and writing achievement while also allowing students to think critically and in justice-focused ways. Such practices allow students to critique gender stereotypes in texts while also examining and even challenging their own implicit perceptions of gender. However,…
